Application at a VTuber Collab Café

Application at a VTuber Collab Café

On August 8–9, 2026, we held Portal ∞ Cafe Vol.0 (Portal Link Cafe) in Osaka. Featuring VTubers Takeshizuku Mai, Tsukumo Mina, and Komainu, the event combined collab café menus, merch, a stereoscopic meetup, and hyper-stereoscopic 1on1 — delivering a highly immersive Portalgraph experience with just a projector and screen.

Challenges

Until now, there was no practical way to deliver stereoscopic presence casually in café-scale venues. Collab cafés typically stop at food, drinks, and merch, leaving little room for a high-quality sense of presence when “meeting your oshi.”

Solution

We did not stop at VTuber collab menus and merchandise. By bringing a projector and screen into the café, we ran a stereoscopic meetup and hyper-stereoscopic 1on1 using Portalgraph.

Guests could enjoy collab menus in the café area, then share the same space with performers through 3D glasses during the meetup, and we made “gachikoi distance” one-on-one interaction possible. Without relying on dedicated permanently installed equipment, we can deliver highly immersive stereoscopic experiences in a wide range of venues.

Stereoscopic Meetup

Across two days, each performer hosted a 40-minute stereoscopic meetup. With 3D glasses, guests enjoyed singing, games, and talk segments with VTubers leaping off the screen — sharing the same space together.

Hyper-Stereoscopic 1on1

After each meetup, we ran hyper-stereoscopic 1on1: Portal Meet. Fans could high-five, hug, and talk at extremely close range — an intimacy that photos alone cannot convey.

Collab Café Menus

Under each VTuber’s supervision, a professional chef developed the collab menus.

Event Merch

We also offered merchandise such as signed postcards, voice-message cheki, and acrylic stands.

Results

By combining meetup, 1on1, the café, and merch in one program, we delivered a high-satisfaction event where fans could eat, buy, and “meet” their oshi in stereoscopic 3D. Performers and attendees alike praised the sense of presence — as if their oshi were truly leaping out right in front of them.

Looking ahead, we want to leverage Portalgraph’s strength as VR you can still see the real world through, and try formats where guests enjoy collab café menus while joining a stereoscopic meetup at the same table.
